Abstract

Cette invention concerne un moulin à cylindres (10) pour pulvériser un matériau fin, lequel moulin comprend un mécanisme de broyage qui présente une pluralité de cylindres de broyage (64) et un concave (66) agissant ensemble pour pulvériser le matériau à l'intérieur du logement du moulin. Le concave comprend une surface de broyage intérieure laquelle présente une portion verticale supérieure et une portion inférieure inclinée vers l'intérieur. La portion inférieure du concave constitue un moyen permettant de retenir plus de particules fines sur le concave pendant le broyage; elle augmente également la surface de broyage. Les cylindres de broyage présentent une forme généralement cylindrique avec une surface de broyage extérieure qui présente une portion verticale supérieure et une portion inférieure de la surface de broyage extérieure. La surface de broyage extérieure du cylindre est complémentaire de la surface de broyage intérieure du concave.
